Where is this conversion used?

Time conversions are used in project planning, computing (where nanoseconds and milliseconds matter), astronomy, and international scheduling. Unlike most units, time uses a mixed-base system (60 seconds per minute, 60 minutes per hour, 24 hours per day). Software developers, astronomers, project managers, and logistics professionals work with time conversions across very different scales — from CPU clock cycles in nanoseconds to geological ages in millions of years.
